Electrochemical, Spectroscopic, And Computational Investigation Of A Series Of Polypyridyl Ruthenium(Ii) Complexes: Characterization Of Reduced States

A series of polypyridyl ruthenium(II) complexes has been synthesized and characterized by H-1-NMR, electronic absorption and voltammetric techniques. Among this series, hexafluorophosphate salts of eight ruthenium(II) complexes were newly prepared. Due to the well-known ability of this class of compounds to assist electro- and photocatalytic reductive processes (such as the reduction of CO2, H+ and NAD(P)(+) models), particular attention has been paid to investigate the nature of their one- and two-electron reduced species through computational and spectroscopic techniques.
